TM1 10.2 – New Feature: Data Flow Diagram

One of the biggest challenges we face when reviewing a TM1 application is getting an understanding of the data flow logics between cubes. There is a number of tools that can help creating some sort of  flowcharts, but none of them is really good.  An alternative is going through all the cube rules, to understand what connects the cubes, but that could very time-consuming.

In this new version of TM1 10.2, this problem has been addressed!  You can now create flowchart diagrams of your TM1 server with ease.

Creating A Data Flow Diagram

When creating a data flow diagram, there are options to create a diagram for the whole application, or a custom diagram highlighting only the selected cubes.

  1. To create a diagram for the whole model, all have to do, is right click in the model design pane and choose “Show Data Flow” and the diagram of the server will be created for you automatically.  Once the diagram is created, you can customise and rearrange everything in any way you want.
  2. The other option is to create a new custom diagram.  Right click in the model design pane, go to new and choose “New Data Flow”. Then you will be represented with a blank canvas and as you drag and drop the cubes, Performance Modeller (PM) will create the links between the cubes.

Thinker arrows mean that, there are more than one links between the cubes, for example, the link between the cubes Promotion Plan and Gross Margin Calculation, as you can see above. You can also group the cubes and customise the diagram in any way you want. Another cool feature is that you can drag a drop folder and bring in the diagram all the cubes in that folder, if they are not already included. This makes it easy to highlight any new cubes created in your TM1 server.

To top everything, this new tool can understand manual rules and feeders and show them in the diagram, like below.

Finally you can export your diagrams into images and include them in presentations or reports.
